I've got one kid and he's 7. Before he came along, I'd have 4 or 5 working at any one time, plus hides tanning, hides smoking, bead work going blah blah blah. Now it's Karate, T-ball, homework...and one, at most two bows at any one time. Worth it though!
I too am getting low on staves. Got some Mulberry and Elm that I cut over X-mas, and a little Hackberry that's ready to go, but I gotta cut some wood! Spied some Bodark over the summer that's not too far up the road from me.
